compared with fig. 3 and fig. 6 of A', microphylla, and similar compar- 

 isons can be made back and forth indefinitely. 



Seward describes and figures a few small fragments from the 

 English Wealden ;it Hastings and Ecclesbourne, which he compares 

 with N.heterophylla Fontaine. The specimen figured shows well the 

 branching habit, and as near as can be judged, is ;i species of Nagei 

 opsis. Since, however, the name A. heterophylla Fontaine becomes a 

 synonym <>f N. zamioides Fontaine, the English fossils may be given 

 the latter name without question, il seems to me.

It remains to notice several forms described as species of Nageiopsis 

 ;iinl which are obviously not related to that genus. The lirst to be 

 considered is Nageiopsis acuminata Fontaine, rounded on a single 

 detached lea I' from near Telegraph Station, Virginia. Professor Fon- 

 taine's figure is quite accurate in outline and the veins are very dis- 

 tinct although he says "veins not seen;" they number about twenty 

 and are thus more numerous than in Nageiopsis, besides being 

 coarser and more distinctly immersed. This leaf appears to be 



identical with the leaflets of PodozamiteS acutifolius of the same 

 author, some specimens of which have been found at this same 

 locality. 



Another form, named N. subfalcata by Professor Fontaine, is also 

 based on a single imperfect specimen which came from near Dutch 

 Gap, Virginia. As figured and described it presents no characters 

 h\ which it can be recognized and none which ally il with Nageiopsis. 



The writer has been unable to locate this specimen in the National 



Museum collections. Professor Fontaine says of it: ''Its position is 



doubtful, and it luaV be a Sequoia, for the footstalks seem to be 



decurrent. They leave imprints on the stem resembling those of 



Sequoia." It is extremely probable that this specimen should be 



referred to Sequoia, as Fontaine suggests.
